Google earth also offers a perimeter for the shape of the area that you can use to measure out the edges or area of a lawn fencing yard the roof and more.
Surface area of roofs on earth.
And even flat roofs usually have a little bit of a slope so you might want to use a roof pitch multiplier once you have your area figured out 1.
Google earth pro was the paid version of google earth it used to cost 400 a year but it s free now.
How roof area is calculated.
Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area.
Calculating the surface area of a sloped roof can be time consuming without the right tools.
One project a lot of people are interested in is living earth roofs.
Approximately three percent of earth s land is urbanized.
The base width is the distance from one corner of your roof to the other at its base on the.
As the other answers have mentioned covering urban areas with white paint would help mitigate the effects of global warming significantly.
Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.
Shingle roofs typically have a life span of 15 30 years.
That gives you 5 590 square feet which is the actual area of the surface of the roof.
Start the project with a roof area calculator.
When i approached him about my plans let s just say he was less than impressed.
You want a roof area calculator that provides accurate estimates to help you order materials such as shingles membrane roofing or ceramic tile.
3 57 505 693 sq km 1 725 1.
Green roofs provide a thermal mass layer which helps reduce the flow of heat into a building.
Green roofs may not reflect as much as a cool roof but do have other benefits such as evapotranspiration which cools the plants and the immediate area around the plants aiding in lowering rooftop.
The most common roofing materials used in the united states include shingles membrane roofing and ceramic tile all of which have different life spans.
After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.
The first thing you need to do is download and install google earth pro.
Our roof calculator uses base length and base width to find the estimated area.
So the actual roof surface if it were laid down flat on the ground would be 1 118 times larger than the footprint of the roof.
The google maps area calculator is not 100 accurate.
But can we do it.
The solar reflectance of green roofs varies depending on the plant types generally 0 3 0 5.
And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier.
